We have covered Atolm GTK theme before and now this beautiful theme gets a PPA which makes it really easy to install and get updates for Ubuntu users. The theme itself got a number of improvements in the latest update. Atolm theme is done by the same artists who created beautiful Orta GTK theme.

Before adding Atolm PPA for installation, make sure you uninstall all traces of Atolm GTK theme you have installed by other methods.

Now, you need to install latest Equinox engine before you start installing Atolm GTK theme. Do the following to install Equinox GTK engine in your Ubuntu(skip this step if you have already installed Equinox GTK theme).

This same repository applies for Orta theme as well which we had discussed above. So if you have already installed Orta theme using PPA, then all you need to do is - update repositories and install atolm-theme package.
